Referring to the drawings, and first to Figure 1,'the numeral 20 designates generally a window opening structure which may be formed of brick, stone, metal, wood or the like. In order to provide means whereby a jalousie structure, generally indicated at 21, may be secured in the opening 20 from the inside of the building, I have provided a jamb liner generally indicated at 22. The jamb liner 22 is formed of a llat plate 23 engageable about the marginal portions of the opening 20. The plate 23 is formed at its inner edge with a right angular locking ilange 24 adapted to be llrmly secured between adjacent window opening elements 25 and 26. The plate 23 extends outwardly and partly overlies the inner portion of an outer trim strip 27. The plate 22 adjacent the outer portion thereof is formed with a right angular inwardly projecting llange 28, against which'a perforate grill 29 is adapted to engage. The grill 29 bears against the inner side of the flange 28 and is secured thereto by fastening members 30.

Imperforate shield 31, constructed in the form of a panel which may be transparent or translucent material, is disposed on the inner side of the grill 29 and is spaced therefrom by means of a gasket 32. The gasket 32 may be formed of asbestos, or other compressible material which will not burn.

The screws 30 hold the grill 29 in place and also extend through the shield or panel 31.

The plate 23 also has formed integral therewith an intermediate flange 33 forming an inner stop member, the purpose for which will be hereinafter described. A sec# ond stop member 34 is formed integral with the inner portion of plate 23 and tapers inwardly so as to assume a wedge shape.

A jalousie frame structure, generally indicated at 35, is adapted to be secured between the flange 33 and the stop 34. The jalousie frame 35 includes a flange 36 extendingroutwardly and confronting the flange 33. A gasket 37 is interposed between the llange 36 of the flange or stop 33.

Clamping block 38 is disposed in the space between the stop members 33 and 34, and a series of clamping screws 39 are threaded through the block 38 and areadapted to bear against the flange 36. The jalousie structure 21 includes pivoted louvers 40 which, when in open position, are dapted to bear at their rear edges against a backing angle member 41. The louvers 40, at their front edges,

are adapted to substantially contact with the inner sideV of the shield 31.

VThe louvers 40 are pivoted as at 42 on an inwardly offset wall 43 formed in the vframe structure 35. The frame structure 35 also includes a llat inwardly projecting plate 44 which bears against the inner side of the clamping block 3S.

Referring now to Figure 2, there is disclosed a slightly modified form of this jamb liner, wherein the stop member 34a is formed with a slot 45 through which the clamping blocks 46 are adapted to be extended. In the present form of the invention, the window sash may be secured to an angle member 47 wit-h one side 4S of the angle member bearing against the inner side of the intermediate stop 33. The bottom portion of each jamb liner is formed with a downwardly and outwardly inclined wall 49 having drain openings '50 for draining any water or moisture atented Aug. 27,V 1 957 sash locking means for- `formed integral therewith.

which enters the space between theange .28 and the A intermediate stop 33.

The lower portion of the jamb liner shown in Figure 2 also includes a downwardly projecting outer flange 51 which may be secured between adjacent window opening elements. Y Y

Referring now to Figure 10, the jamb liner 22 shown therein is identical with the liner shown in Figure 1. The liner is here disclosed as b eing usedd with a new building 52 inwardly of stopSS. A jalousie frame The connecting wall 70. A louver f spacer block 72 disposed between iangeV structure having two-by-fours 86 disposed about the margin of the window opening.

Referring now to Figure 11, the jamb liner 22 is identical with that shown in Figure l, but the window opening structure includes a buck frame 87 to which the liner 22 is securedby any suitable fastening means.

Referring now to Figure 12, there is disclosed a frag- 1mentary sectional view of a modified form of jamb liner.

Referring now to Figure 13, there .is disclosed a modil iied form of clamping block 92, which is provided with a plurality of parallel tongues 93. Where the block 92 is used this bloclr is substantially shorter than the distance between the upper and lower portions of the jamb liner, and the inner stop member 34 is provided with corresponding notches through which the tongues 93 are adapted to loosely engage.

Referring now to NFigure 14l there is disclosed a modifled form of jamb liner embodying a pair of spaced plates-94 and 95 connected together by a U-shaped meinber 96 which projects inwardly from plates 94 and 95. Plate 94 is formed with an inner stop member 97 and. plate 95 is formed with an outer stop member 93. Channel member 96 forms anintermediate stop member against which one side 99 of an angle member 164i is adapted to vbe tightly clamped. A block 181 is disposed between stop member V96 and stop member 97, and clamping screws 102 are threaded `through block member 101. Block member 101 includes a longitudinal tongue 103 disposed between the outer edge of angle side 9) and the inner side of plate 94. Block 101 is adapted to be inserted from an opening formed in the adjacent right angularly disposed liner plate 94. Angle member is adapted to have secured thereto a sash .1M which is a fragmentary or upper sash, with a conventional louver structure 105 disposed below sash 194.

Referring now to Figures 15 and 16, there is disclosed a jamb liner structure generally indicated at 106, which is similar Vto that shown in Figure 14 with the exception that the inner and outer stop members 107 and 108, respectively, are formed with notches 109 and 110, respectively, through which relatively short clamping block 111 shown in Figure 16 are adapted to be inserted. As shown in Figure 16, theangle member 100 may have secured thereto a channel member 112 and a window sash may be secured within the channel member 112.

In the event'the window sash is Vto be raised or lowered, the angle member shown in Figure 17, indicated at 113, maybe used.V This angle member 113 is provided with openings 114 through which the bolts 115 extend and bearagainst a gasket 116. The bolts 115 are Vwherein the outer edges of the louvers threaded through clamping blocks 117.

In use of this invention, where an old building is to be converted, the jamb liner shown in Figure l is used. The liner 22 is secured within the window opening and the grill 29 with shield 31 are secured to flange 23. rThe jalousie frame structure 35 is clamped against stop 33 by bolts 39. `Where the jalousie 21 is applied to a relatively tall building, if any of the glass louvers should become broken, the :broken pieces will be held against dropping by means of theV shield 31 and the grill 29.

In the event a bomb attack is expected, the louvers a@ may be turned to open position as shown in Figure l, 4l) bear tightly against the shield 31. l InV this` manner, the louvers will reinforce the shield so that the outer pressures will not collapse the shield. The mounting of the grill 29 and the shield 31 will prevent any of the fall-out material from entering the building. In this manner, the rnounting of the invention in window openings of either old or new buildings, will provide a protecting means for protecting the occupants of the buildings against any radioactive fall-out material.
